FAQ
Common questions
What makes this a chronogram?
Its branch lengths are presented on a time scale, rather than only showing the order of branching.
Why include macaque and baboon?
They provide a more distant comparison branch for the selected apes.
Are the dates a research result?
This is an illustrative example. A research tree should identify the data and method used for its dates.
